Сторінка 273 - It is extremely improbable that when we come to understand the true nature of electrolysis we shall retain in any form the theory of molecular charges, for then we shall have obtained a secure basis on which to form a true theory of electric currents, and so become independent of these provisional theories.
Сторінка 133 - It is dark in the veins bringing the blood from the body to the heart, in the right side of the heart, and in the pulmonary artery. The...
Сторінка 314 - ... the currents in the moving coils of the armature have also their effect on the resultant field. There are in general two independent variables in a dynamo machine, the current around the magnets and the current in the armature, and the relation of EMF to currents is fully represented by a surface.
Сторінка 289 - Memoranda of the origin, plan, and results of the field and other experiments conducted on the farm and in the laboratory of Sir JB Lawes at Rothamsted, Herts.
Сторінка 313 - Dynamo-Electric Machines." By John Hopkinson, D. Sc. , FRS, and tdward Hopkinson, D.Sc. Omitting the inductive effects of the current in the armature itself, all the properties of a dynamo- machine are most conveniently deduced from a statement of the relation between the magnetic field and the magnetising force required to produce that field. This relation given, it is easy to deduce what the result will be in all employments of the machine, also the result of varying the winding of the machine...
Сторінка 369 - The model was received at the Office in the course of the month, and was at once set in action ; the results of the preliminary trials when obtained being referred to a Committee consisting of the late Prof. HJS Smith and Prof. Stokes, who, on July 5 following, submitted to the Meteorological Council a iavourable report on the performance of the model.
Сторінка 565 - CATALOGUE OF THE SCIENTIFIC BOOKS IN THE LIBRARY OF THE ROYAL SOCIETY.
Сторінка 207 - ... duration of the ENE wind is eighteen times as great as that of the NW wind. The winds, also, whose relative durations are above the average are limited to the four points NNE, NE, ENE, and East, The barometer, standard thermometer, and wet-bulb thermometer were read six times each day, namely at 6 AM, 8 AM, 2 PM, 4 PM, 10 PM, and midnight, excepting on Sundays, Christmas Day, and Good Friday, when these instruments were read at 6 AM and 2 PM only. These latter readings, though recorded in the...
Сторінка 389 - Speaking broadly, parents of different statures transmit a blended heritage to their children, but parents of different eye-colours transmit an alternative heritage. If one parent is as much taller than the average of his or her sex as the other parent is shorter, the statures of their children will be distributed in much the same way as those of parents who were both of medium height. But if one parent has a light eye-colour and the other a dark eye-colour, the children will be partly light and...
Сторінка 181 - Substituting for the bath an oily pad, pressed against the free part of the journal, and making it so slightly greasy that it was barely perceptible to the touch, he again found considerable regularity in the results ; these, however, were very different from those with the bath. Then with intermediate lubrication he obtained intermediate results, of which he says : — " Indeed, the results, generally speaking, were so uncertain and irregular that they may be summed up in a few words. The friction...
